OILER.

Application filed December My invention relates to oil cans intended for oiling machinery. l

The main purpose of my invention 18 improve the function of the can when dlstributing oil in an upward direction without seriously interterring with oil distribution when the spout is sloped downwardly.

A further purpose is to provide an extension of the spout within the can having a pocket or flare to enlarge theinlet and to catch and hold oil when the can is tilted.

A further purpose is to correlate the shape ofthe can and the position of the inlet to a spout extension within the can so as to secure the best average feeding conditions from the can in all positions.

A further purpose is to provide for a residuum of oil within the can for the purpose of maintaining an oil level in all positions constantly above my special outlet and to secure maximum air compression. V "A further purpose is to provide aspring bottom oil can with a closure carrying a spout continuous above and below the closure and terminating in a bulb having arelatively constricted'lower opening to trap oil within the bulb when'the can is tilted andtobring pressure upon the oil trappedby means of the springbottom. V p

Further purposes will appear in the specification and in the claims.

I have preferred to illustratemy invention by but three iorms among many in which the invention might appear, selecting forms which have proved to be practical, ellicient and reliable, and which at the same time well illustrate the principles of my inven- .tion.

no provision for catching extra oil in the extensions while the cans are being tiltedin order that the cans will continuetheoiling function reasonably when tilted excessively or turned upside down. The shape of'the canhas not cooperated to, the best advantage with the rearwardly extended spout and the oil has not been fed into the spout to the best advantage.

In overcoming these and some otherdefects I have added a number of features, each of which is separately-beneficial and all of which cooperate to secure highly bene ficial results. I i l In all of my illustrations I have preferred to form the can body 5 with a relatively contracted upper contourfi and a relatively swelled lowereontour 7 in order that much the greater part of the oil many be contained in the lower part. l

The screw closure 8 carries a spout 9 which shown as straight above gbut which, of course, may be curved if preferred. The

spout is extended effectively down through the closure integrally or by a connecting tube, to form an internal depending feed tube 10, terminating in a bell, flare, bulb or cup 11-open at the bottom at 12. The feed tube and nozzle are continuous in the sense tlnitthere is no leakage between them but need not be ofthestme cross section evenat their meeting e nds.- y

The bottom opennig 12 is preferably small,-

er in cross section than is the adjoining inthe cupLwill be caught or trapped byithe in wardlyiextending edge 13 of the cup as the can is excess'vely tilted for use.-

This trapping of oil sup )lies any predetermined quantity'of oil, sutllcient for normal use of the can in this position evenwhen the quantityof oil in the can relatively low and is too low to submerge the opening in theife ed tube asthe can is tilted. The wider the open'ng thoflower the depth of oil at.

t'ltinglof the can with vthe oil depth below v p the intended minimum. Though oil cans have been proposed 111i l/Vith the shape selectedandin the position shown in F1gure 1 the; volume of the oil space within the lower third of the height of the ,space is approximately equal to the volume of the remainingtwo-thirds of this space.

As a result and as illustrated in Figures 4 and 5 with the preferred minimum of oil, a I

' which oil will still be pocketed during the trifle over half the total content of the can, the oil level will be nearly uniform at the limits right-side up and up-side down and will be high between these limits. This sea partial charge of oil sufficient for ordinary oiling purposes.

Considering first the form of Figure 1 :Thecup is shown with its bottom, opening about onethird of the can height above the bottom of the can to cooperate with the height of oil secured by the shape of the can above noted. Where advantage is not to be "taken of this, it may be placed at any desired height frointhe bottom 14 aspredetermin'ed by thedepth of oil which the designer intends to require in the can for continued normal operation of the can. So long as the bottom of the cup is covered, oil may be ejected in the position shown for vertical oiling. v

Even in this case it is desirable to maintain a considerablequantity of oil in the can if vertical oiling is to be had and even for other oiling, order that the air space may be kept low and that the necessary pressure for ejection may be secured by a normal. .flexing of the bottom of the can. WVith the bottom of the cup just covered or withany greater oil depth, tilting of the can will continue to submerge opening I from thecup into the nozzle until the can has tilted beyond the horizontal. WVith further tilting even ifthis cover 7 of oil be lost,

sufficient oil depth will stilllie over the loweredge of the cupto retain a considerable charge of oil, All of the oil so trapped will flow down into the spout-and thus provide for. oilings from a downwardly sloping spout in proportion to the size of the pool of oil caught by the; cup during the turning movement. This quantityof oiland the slope of spout at which it will flow out maybe controlledby variation inthe size and shape of the cup as well as by reducing the opening in the bottom of the cup to any'desired size.

. an easier slope from the cup to the spout.-

In the form shown in Figure 2 the contour of the cu'pll' has been changed to provide In tlie'foi'm shown in Figure 3 the same general cond tions are true as in the form" shown in Figures. 1 and 2, with the ditfer ence,'however, that a perforated shield or baflie is provided about the belhflare' or cup" 11 so that the oil is trapp'edabout the flare or cup as the can is being tilted. i

The extension of the nozzle here'permis- "sibly lies somewhat lower in the can and is" shown at 11 as more nearly spherical and as having a relatively smaller opening than the other forms. These differences are intended to illustrate the capability of different forms of bell, flare or cup to secure the results, but no attempt has been made to show all the forms which would be useful for this puroose. 1 About the center is shown a bafiie 16 of annular shape, and having relatively small openings 17 at th e'base of the battle communicating with the outer part of the can.

' When the can isiested onfits base the oil will flow in'through the bafiie openings 17 and willfill up the entirebottom to a uniform height. The openings, however, are too small toa'llow the oil to flowout rapidly with the result that during brief tilting of the can the baftle'is initially eifectivein confining the oil within it and increasing the height of the sloping pool of oil about the cup or flarejust as if it were the side wall of the can. The balile may be terminated at 20 soas to allow the oil to flow over its outer wall freely when the can is tilted to or but slightly beyond the horizontal, or, preferably, it may be inwardly turned at the end at 18 so as to maintain a relatively artificial height of oil throughout a much larger tilting range as desired.

In operation, where the baffle is used, an

artificialheight of oil is retained about the flare,bell, or cup so as toin'crease the quantity of oil available for use where the total quantity of oil in the can is rela-tively'low and the canis being used in tilted position. On the other hand normal height of oil is resuined by reason of the percolation of oil through the aperture or apertures 1'11 soon after the can is rested upon itsbase. The use of the baflle secures part of the same benelit'that is secured by the conformation of the can and, from this standpoint, might be considered as a'substitute for it; but it is also beneficial even whei'e'the cooperation of the can conformation is secured, being then supplemental to it in thecoinbination.

In View of-my disclosures, modifications and changes of my structure will suggest themselves to others skilled in the art suiting individual whim or special need, or which are desirable to others because they-secure all or part of the benefit of my structure without copying it. I, therefore, intend to cover here all such modifications as come within the reasonable spirit and scope of my claims p w Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In an'oil can, a can body in combination with a closure for the body, a spout pass ing. througlr'the closure and an extension from the spout in fluid communication therewith,terminating at a height from the hottom corresponding approximately with the horizontal plane which separates the inte-- rior capacity of the can into equal volumes.

2. In an oil can, a can body having a bottom adapted to be sprung toward the top of the can to discharge the contents and having approximately half of the capacity of the can in the first third of the height of the can, in combination with a closure for the can, a spout and an extension from the spout down into the can having an opening directly facing the bottom'at a height approximately a third from the bottom.

8. In an oil can, a can body, a closure for the body, a spout and an extension from the spout down into the can, terminating in an enlargement internally flanged to form an opening of smaller cross section than the adjoining part of the enlargement and having the walls of the enlargement sloping downwardly and outwardly to provide for easy thevolume of the can lies below the level V of the opening.

5. In an oil can, a can body, a closure for the body and a continuous spout extending,

above the closure to the outlet and also below the closure, a bulb at the lower end of the spout extension well down in the body of the can communicating with this spout, open at. the bottom and having an inwardly turned lower edge aboutthe opening and a resilient bottom effective to bring pressure upon oil trapped in the bulb.
